' Improvements in Evaporators and Furnaces,

of which the following is a specification, refer ence being had to the accompanying drawings. My invention relates to an improvement in evaporating-pans and furnaces for boiling molasses; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed outin the claims.

In the drawings, Figure 1 is a top plan view. Fig. 2 is a vertical longitudinal sectional View taken through the evaporating-pan and the furnace. the evaporating-pan. Fig. 4 is a detail view showing the manner of connecting the parts of the furnace together.

A represents the furnace, which has sides B, made of cast or wrought metal, and pro-' vided attheir ends with recesses 0. On the innersides of the sides are made grooves D and E. The grooves Dare inclined upwardly and are located at asuitable distance from the inclined lower rear edges of the sides, and the grooves E are horizontal and are located at a suitable distance above the lower edges of the front ends of the sides. r

F represents a bottom plate, which is located between the'sides B, and the edges of which enter the groovesl) of the sides.

G represents the frontside or wall of the furnace, which is made of cast or wrought metal, and is provided at its ends with projec- I smoke-pipe.

tions or shoulders 9, that enter the recesses G of the sides. This front wallis provided also with a lower opening, H, forming the door to the ash-pit, and a door, I, above the opening H, forming a door of the firebox. The rear wall, K, of the furnace is also formed of wrought or .cast metal, and is provided with project-ions that enter the recesses at the rear ends of the side walls, and has a verticallyprojecting collar, L, for the attack ment of the The side and end plates or walls of the furnace are secured together by vertical bolts M, which pass through aligned openings made in the ends of the plates, as shown,

Fig. 3 is a transverse sectional view of p the furnace together, and permitting them to be readily taken apart, by first withdrawing the bolts. The grate-bars N have their ends 'secured in the grooves E. The openings H and I are provided with suitablehinged doors. By opening or closing the door H the draft may be regulated, and the door Ipermits fuel to be fed to the fire.

N represents the evaporating-pan. The sides 0 of the pan are made of wood and are provided on their opposing sides with vertical grooves I. The bottom and ends of the pan are formed of sheet metal, the ends of which are bent at right angles and secured in theend grooves 1?, while the edges of the bottom of the pan are bent upwardly at right angles and bear against the lower outer edges of the sides 0 and are securely tacked thereto. Bracestrips S are placed under the bottom at the sides thereof. The said brace-strips are triangular or convex in cross-section to form the inclined beveled sides a and the fiat bottom sides 5. Vertical bolts T pass through the sides 0, through the edges of the bottom plate, and through the strips S, and serve to clamp the bottom plate firmly to the lower edges of the sides 0, so as to prevent the pan from leaking. The pan is divided into three compartments by means of transverse vertical partition-walls U, which are made of sheet metal and are inserted in the intermediate grooves, P, and the said partition-walls are provided atone side with vertically-movable gates V. Transverse bolts XV pass through the side walls and connect the sametogether, thereby firmly bracing the pan against lateral strain. The transverse bolts at the ends of the pan are on the outer sides of the end walls thereof, and thus serve to brace the latter. The compartment X at one end of the evaporating-pan immediately overthe fire-box is left clear, and forms the skimming-chamber,in which the impurities and froth,which arise from the surface of the molasses while being boiled,are skimmed off. The other compartments, Y and Z, are each divided by means of vertical plates Z ing nearly but not quite across the evaporating-pan, leaving openings alternately at opposite sides thereof.

into tortuous channels, the said plates extendthereby firml y securing the sides and ends of The operation of my invention will be readily understood by personsskilled in the art from the foregoing description and by reference to the accompanying drawings.

Having thus described my invention, I claim The furnace for evaporators,comprising the side walls 13, provided 011 their opposing faces at one end with the horizontal grooves E, and the inclined rearwardly-extending grooves D, communicating at their lower ends with the grooves E, the front end wall, G, having the doors H and I, the rear end wall, K, having the vertically-projecting collar L for the at tachniont of a smoke-pipe, the bottom plate having its edges securedin theinelined grooves D, and the gratebars having their ends socured in the grooves E, the side and end walls being bolted together and thereby rendered separable, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
